I've been homebrewing for a while and have been kegging in Sanke kegs since the beginning. The one issue I have though is developing a pipeline. Usually, I just try and time my fermenting to match when my kegs on tap will blow, but even if I do this right, there's maybe 3 days or so where my taps are "dry" while I force carb the kegs.

So, I'm thinking about buying a second CO2 Bottle and associated equipment, then kegging/force carbing the kegs before storing them somewhere prior to moving them into the kegerator. After force carbing the keg for a few days, I would disconnect them for storage.

My question is, how long would the beer stay good with this kind of pipeline setup? What about storage temperatures? I don't currently have excess refrigeration space to store excess kegs. If it's paramount that I store them at serving temperature, I could always buy a chest freezer and modify it with an STC-1000, although I'm not sure how cool my wife would be with more stuff in the garage.

I have a 'charging' station in my basement. It's a 20# CO2 tank with a 'spider web' of gas lines. I carb my beers warm. Needs a little higher PSI, but no worries. Depending on the beer, you can go months with storing in a 'not too warm' place. My basement hovers in the 60's, so no worries there. Perfect way to keep a pipeline. Figure a keg is just a big bottle. Most bottlers don't keep all their beer in the fridge. It's conditioning.

Further follow on question, with Sanke keg couplers, is there any way to easily block out the beer outflow so the CO2 can force carb the keg without pushing beer out and up a line that then needs cleaning?

I'm guessing it would take a specialized coupler that's not readily available.

How do you share the gas among those lines? A manifold? How many can you connect?

Yes, there is a manifold that has 5 'whips' coming off of it. Works great to keep my pipeline full. I have the capability of keeping a cold extra keg in my keezer. Nothing better than blowing a keg, simply hooking up another carbed/cold keg, removing the empty and replacing with a carbed warm one. Next day, I'm ready for the next one to blow.
